Nick Grimshaw has joked about Harry Styles being left out of the trailer for his new movie Dunkirk.

Normally, you wouldn't expect someone with a small part in a film to appear in the promo, but One Direction fans are NOT happy about Hazza's pretty face [acting skills] not being showcased in the trailer.

During his Radio 1 Breakfast Show this morning, presenter Grimmy said: "[Director] Christopher Nolan has obviously made some incredible films, some real epic films and giant sets and stuff.

"I think the biggest challenge to date is gonna be the wrath of Harry Style's fans on Twitter.

"If he doesn't put him in enough, or puts him in too much, or there's a bad angle, he might never be able to work again. Nolan's life won't be worth living."

The film, which is due out next July, will depict the evacuation of the British Expeditionary Force from the beaches around the Northern French town of Dunkirk over three days in June 1940.

The film features the likes of Tom Hardy, Kenneth Branagh, Mark Rylance and Harry Styles, though none of the A list crop can be seen in the short trailer.

The cryptic official clip opens with a scene showing foam washing up on the beach before soldiers begin to appear and bodies can be seen buried under the sand.

"At the point of crisis," "At the point of annihilation" and "Survival is victory" appear on the screen between each short scene.

"He seems remarkable ... one of those people who has - Sean Penn has it too - a kind of panache. I look at them and think, 'How did you get that? How do you get so that life is easy?' But he has got a lovely, lovely character. It's a gift."
